Part number HQ4384 is an AS568-384 black Buna-N (Nitrile) 70 Shore A Quad-Ring supplied with an inside diameter of 14.975 in (380.37 mm), a cross section of 0.21 in (5.33 mm), and an outside diameter of 15.395 in (391.03 mm). A quad-ring delivers lower friction and better sealing stability than a comparable round-section o-ring.
Buna-N (Nitrile) is specified for reliable performance in both static and dynamic service, an economical choice for high-volume maintenance programs. Expect good resistance to petroleum-based oils, many alcohols, and water. Service temperature is rated from -40°F (-40°C) through 250°F (121.1°C). Verify compatibility before use with ketones or automotive brake fluid. The profile itself contributes a parting line located away from the sealing surface and lower compressive load required to achieve a seal.
Maintenance and OEM teams specify it across fluid power, agricultural equipment, and hydraulic and pneumatic systems.
Reference part number HQ4384 when ordering; the item is sold individually. Application requirements vary, so validate compatibility with your process conditions prior to installation.
